lib: sbi: Move trap delegation setup to sbi_trap.c

Browse Source 
Currently, the trap delegation setup is part of sbi_hart.c and
called via sbi_hart_init() whereas the per-hart trap (aka exception
and interrupt) handling is part of sbi_trap.c.

Move trap delegation init to sbi_trap.c and call it via new
sbi_trap_init() from both cold boot and warm boot path. This
way trap delegation setup is in same place as trap handling.
